Hi Dave,

Today's linux-next build (powerpc allyesconfig) failed like this:

drivers/gpu/drm/drm_gem.c: In function 'drm_gem_mmap':
drivers/gpu/drm/drm_gem.c:519: error: '_PAGE_CACHE_WC' undeclared (first use in this function)

Caused by commit 33b801854540a4f5205c0b2b4b91987e7f21af08 ("drm: GEM mmap
support").  I tried to revert just that commit, but it lead me down a
road of dependent commits, so I have reverted the whole drm tree for
today.

_PAGE_CACHE_WC appears to be defined only for x86 and, before the above
commit, was not used outside arch/x86.
